CHAPTER 1 | INTRODUCTION The SmartCtrlTM interface modules are designed as a unique combination of standard inputs and SuperPortTM outputs to create a system whereby a single interface card would connect to a single test chamber. SmartCtrl modules use a single cabinet and power supply, one interface card and one decoder card to simplify system design and increase savings as additional test chambers are added. Connect one card with one test chamber using a universal cable and a connection panel. The connection panel is housed in a stainless steel enclosure that mounts securely on the test chamber base. Convenient Molex connectors are provided for both inputs and outputs. Inputs and outputs are not restricted to any particular function. Each is clearly identified by the I/O number assigned in the MED-PC® software.

The Port System

Although MED-PC interprets ports and bit values automatically, a basic understanding of these concepts is helpful while setting up a system. Ports allow each SmartCtrl card to communicate with a computer via a specific address in memory. The port number is selected by a combination of switch settings that determine the desired port value. The location of the switches is discussed later in this manual. Generally, modules will be shipped from the factory with prearranged values according to the following rules. Each SmartCtrl card installed in the same cabinet must have a unique port assigned to handle both inputs and outputs. Inputs are handled like any other standard input module. The first SmartCtrl card is assigned to port 780, the second to port 781, and so forth up to the sixteenth card at port 795. Outputs are handled as SuperPorts. All cards are assigned to port 792, with a different offset address for each card. The first SmartCtrl card is assigned to offset address 0, the second to offset address 2, the third of offset address 4, and so forth up to the sixteenth card at offset address 30.

Modules shipped from the factory will often have a tag indicating the port and offset settings. For example a DIG-716 module may be tagged “780,0” to indicate that the input port is 780 and the output offset address is 0 (output port is always 792). A DIG-716B module may be tagged “781, 2/3” to indicate that the input port is 781 and the first eight outputs are at offset 2 while the second eight outputs (outputs 9 – 16) are at offset 3.

Note: Please be sure to turn off the cabinet’s power before inserting or removing any SmartCTRL or other cards in the cabinets as failing to do so may result in damaged equipment. SmartCTRL or other cards must be installed face up, i.e. with the text on the face panel readable from the front of the cabinets. Failing to do so will result in damaged equipment.

Binary Numbering System

The binary system enables each port to input or output the status of 8 control lines simultaneously. That is, each group of 8 or fewer control lines is represented by a binary “word” with an equal number of bits. Each bit can only be in one of two states, “0” or “1” (OFF or ON). To distinguish one bit from another, each has a weighted value. In the decimal system, each bit (digit) can be in one of ten states (0 to 9), and the weighted values increase by a factor of 10. For an example, see Table 1.1.

Table 1.1 – Decimal System

Digit “Number” 6 5 4 3 2 1 0

Weighted Value 1,000,000 100,000 10,000 1,000 100 10 1

The number 735 may be thought of as the sum of each digit times the weighted value or, (7 x 100) + (3 x 10) + (5 x 1). A comparable illustration in the binary numbering system is shown below.

Table 1.2 - Binary Numbering

Bit Number 7 6 5 4 3 2 1 0

Weighted Value 128 64 32 16 8 4 2 1

In binary each bit can only be 0 or 1, therefore the number 10010 has a digital value of 18, that is, (1 x 16) + (0 x 8) + (0 x 4) + (1 x 2) + (0 x 1).

It is not necessary to be proficient in the binary numbering system. Simply keep in mind that each input or output is assigned a bit value of 1, 2, 4, 8, 16, 32, 64 or 128 and a port value from 780 through 795 for inputs and 792 for outputs. In addition, outputs are assigned a second address known as an offset address from 0 through 30. Note, offsets up to 254 are possible with regular SuperPort modules, but are not appropriate for SmartCtrl systems.

Interface Cabinets

SmartCtrl modules may be installed in four models of interface cabinets: SG-6010, SG-6080C, SG-6510D and SG-6080D, all shown below. All are also available in a 220 Volt 50 Hz version with model numbers SG-6010A, SG-6081C, SG-6510A and SG-6081D respectively. Each includes regulated power supplies with outputs of +/- 15 Volts DC and + 5 Volts DC. The SG-6510D and SG-6080D also include a 28 Volts DC power supply.

The SG-6010 and SG-6510D are full size cabinets capable of holding up to 18 single-width modules or cards. This allows room for up to 16 chambers and the DIG-700G decoder card. The SG-6080C and SG-6080D are tabletop sized cabinets capable of holding nine single-width modules or cards. This allows room for up to eight chambers and the DIG-700G card.

The SG-6010 cabinet may be placed in any standard 19” equipment rack or it may be used as is. Because the cabinet is perforated for cooling, it is susceptible to spills. Therefore, if it is to be used as a stand-alone unit it is recommended that is be placed in an enclosure. Three sizes are available from MED Associates: SG-6500 Single, SG-6501 Double and SG-6502 Triple.

CHAPTER 2 | DIG-700P2-R2 PCI INTERFACE CONNECTION PACKAGE

Hardware Description

This package is recommended to connect the SG-6080D and SG-6510D interface cabinets to most Windows® compatible computers with an open PCI-E slot. It includes one DIG-704PCIe interface card, DIG-700C ribbon cable, and DIG-700G decoder card, as shown in Figure 2.1.

Wiring Instructions

The decoder card may be placed in any slot in the interface cabinet but will generally be found on one end or the other to facilitate connection to the computer.

1. Using the DIG-700C ribbon cable connect the DIG-704PCIe interface card located in the computer to the DIG-700G decoder card located in the interface cabinet. Note, both ends of this cable have identical keyed connectors that will only plug in one way. Be careful not to force the connector, as doing so could bend a pin and cause the system to malfunction. It is not advisable to use a longer ribbon cable.

Figure 2.2 – Wiring the Interface Package

2. Using an SG-210CP 2-pin Molex cable, connect the polarized Molex connector on the DIG-700G decoder card to a 28 VDC power supply. Several examples are shown below. If the DIG-700G decoder card is connected to a conventional power supply, connect 28 V to the round hole of the polarized connector and ground (GND) to the hole with the square end.

CHAPTER 3 | SMARTCTRL PACKAGES

DIG-716P1 SmartCtrl 4 Input 8 Output Package

This basic SmartCtrl™ package includes one DIG-716 interface module, one SG-716 connection panel, one SG-210CB control cable, and one power cable. A 25' (7.6 m) power cable (SG-210CP-25) is supplied for the first test station in each group of four. Subsequent stations are daisy chained together with 8' cables (SG-210CP-8).

The DIG-716 interface module and SG-716 connection panel provide four inputs and eight outputs that may be assigned any function and connected to any accessory on the test chamber.

DIG-716P2 SmartCtrl 8 Input 16 Output Package

This expanded SmartCtrl™ package includes one DIG-716B interface module, one SG-716B connection panel, one SG-210CB control cable, and one power cable. A 25' (7.6 m) power cable (SG-210CP-25) is supplied for the first test station in each group of four. Subsequent stations are daisy chained together with 8' (2.4 m) cables (SG-210CP-8).

The DIG-716B interface module and SG-716B connection panel provide eight inputs and sixteen outputs that may be assigned any function and connected to any accessory on the test chamber.

Wiring Instructions

The wiring instructions for both interface packages are the same, the DIG-716P1 Package is shown in the illustrations below.

1. Using an SG-210CB cable, connect the DIG-716(B) interface module to the SG-716(B) connection panel.

Figure 3.1 – Connecting the DIG-716 to the SG-716

CHAPTER 4 | SWITCH SETTINGS Interface cards are addressed correctly prior to being shipped from MED Associates, Inc. It should only be necessary to change the addressing of an interface card if additional cards are being added to an existing system. In the table below the name of the specific dipswitch will be referenced. If a dipswitch is referenced, then that switch should be set to the CLOSED position.

Figure 4.1 – Port and Offset Dipswitches

Port Settings

The input port settings are set via SW4 and SW5. The card connected to test chamber 1 is set to port 780 as illustrated in Figure 4.2. Set the card connected to chamber 2 to port 781, and so on. Refer to Table 4.1.

The output port setting is hard coded to 792 / 793 and does not need to be set with the dipswitches. Remember when running the MPC2INST configuration program for MED-PC only the 792 is entered.



- 10 -


Offset Settings

The offset setting is set via SW1. The offset value obtained from each switch that is in the CLOSED position is as follows:

A1 = 2 A2 = 4 A3 = 8 A4 = 16 A5 = 32 A6 = 64 A7 = 128 A8 = NC

The first card should be set to offset 0 (all switches OPEN, as illustrated in Figure 4.2), the second card to offset 2 by setting A1 to CLOSED, the third card to offset 4 by setting A2 to CLOSED (as shown in Figure 4.3), and so on. Table 4.1 illustrates the port and offset settings for up to 16 cards in a standard SmartCtrl system. When adding a SmartCtrl card to a system with existing standard and/or SuperPort modules, simply select input ports and output offset addresses that do not conflict with existing cards and manually add the port, offset and bit values to the input and output configurations.

Toggle and Level Input Setting

The SW2 switches can be set to “L” for Level or “T” for Toggle. The default switch placement is Toggle, as shown in Figure 4.4. This setting provides a single input no matter how long the input is held. When used with a response lever for example, this requires the animal to both press and release the lever before another response could be detected. The input may occur on either the press or the release depending on the switch contact (Normally Open or Normally Closed) and the input setting (Normal or Invert). Because the input of the card is filtered against switch bounce and latched until polled by the computer, even the shortest contact (or contact break if in the Invert mode) will not be missed.

A level switch placement for any input setting results in an input being detected each time the card is polled for as long as the input is maintained. (In MED-PC this occurs on each interrupt and is determined by the resolution setting in MPC2INST. See the “MED-PC IV User’s Manual” for details). This may be desirable when using photobeams or when timing how long a response lever is held. NOTE: Because of other programming considerations it is often easier to time a response lever by wiring both NO and NC contacts to Normal/Toggle inputs and simply measure the elapsed time from response 1 to response 2.

Figure 4.4 – Toggle and Level Dipswitches

Normal and Inverted Input Setting

The SW3 switches are used for setting the normal and inverted input setting. The switches are labeled “+” for normal and “-“ for inverted. The default switch placement is Normal, as shown in Figure 4.5. The Normal setting is designed to work with a normally open contact, such as that found in rodent or primate response levers, and will cause an input to occur when the response lever is pressed or the switch contact is closed. Change to Invert if it is desirable for an input to occur when the lever is released or the switch contact is opened. Use Invert with normally closed pigeon keys to produce a response when the key is pressed and with the photobeam input if an input is desired when the beam is uninterrupted instead of broken.

CHAPTER 5 | SMARTCTRL CONNECTION PANEL PINOUTS / OFFSETS

Input Connector Pin Out

The SG-716 SmartCtrl connection panel consists of four 3-pin mini-Molex connectors for inputs and the SG-716B has eight 3-pin mini-Molex connectors for inputs. The three-pin input connectors are wired as shown in Table 5.1.

Table 5.1 – Input Connector Pin Out

Pin Function

1 Ground (GND or “-“)

2 Input Data Line

3 28 Volts DC

Note: The 28 Volts DC is present at the input connector to power such input devices as photobeam controls, contact lickometers, head entry detectors, etc. When wiring input switches be certain that 28 V is not connected to the input data line. Doing so could damage the card.

Connecting a Coulbourn lever will result in a direct short between pin 1 and pin 3. To prevent this, remove the wire from the NC contact on the Coulbourn lever or from pin 3 on the Molex connector. The 28 V supply can also be removed from all input connectors by removing a single jumper wire on the connection panel circuit board. This will be done at the factory at no additional cost if requested when placing an order.

Output Connector Pin Out

The three-pin input connectors on the SG-716 and SG-716B are wired as shown in Table 5.2. Each output is capable of switching up to 3 amps at 28 Volts DC.

Table 5.2 – Output Connector Pin Out

Pin Function

1 Ground (GND or “-“)

2 Output Control Line

Input and Output Offsets

As with other input and output modules, each data line (input) or control line (output) is assigned a binary bit value. The input and output offset values and the corresponding bit values for the SG-716 are shown in Table 5.3. The input and output offset values and the corresponding bit values for the SG-716B are the same for Inputs 1 – 4 and Outputs 1 – 8. Therefore, Table 5.4 contains the values for Inputs 5 – 8 and Outputs 9 – 16 only.
